Electronic Valve Actuation in Combustion Engine

This thesis provides a method for electronically actuating the valves used in an internal combustion engine. This method for valve actuation looks at utilising the expected change to a 42V standard in motor vehicles. It also provides a simplified model elaborating how this principle works.

The advantage of electronic valve actuation is that it provides an easy method of infinitely varying the valve timing in internal combustion engines. The relationship between the desired open and shut intervals of the intake and exhaust valves vary with respect to engine speed. The current methods of valve actuation involve using an outdated mechanical method that ensures that the timing cannot readily be changed to suit the vehicle’s needs.

Voice recorder using ADC and MicrocontrollerCreate a voice recorder using a PIC or a microcontroller and ADC. Use some conditioning circuits to condition the microphone output and feed it to the ADC. The converted values can be stored in some kind of memory. Samsung has...

Novel Application of Diffractive Optical Elements in Optical SystemsDammann proposed the special type of diffraction grating which is periodic in nature together with binary phase for achieving a high splitting ratio. Later on, researchers proposed different kinds of methods for improving the performances. Dammann Gratings can be used in many areas,...
